Description
Technical field
The present invention relates to it is a kind of be used for interconnection, guiding hot gas component the sealing surface being mutually directed towards it
Between the metal flat sealing element that is packed into, it has being extruded when being packed into sealing element, close with multiple metals stacked on top of each other
The sealing plate of sealing and multiple hot gas break-through mouths, wherein, the sealing plate between at least two adjacent hot gas break-through mouths has
By sealing plate contact pin that break-through mouth is spaced-apart in the vertical view of sealing plate.
The present invention especially further relates to the sealing element of the exhaust gas region for internal combustion engine, preferably in exhaust-driven turbo-charger exhaust-gas turbo charger
On flange seal part, such as between exhaust elbow and exhaust-driven turbo-charger exhaust-gas turbo charger or the increasing of multistage exhaust-driven turbo-charger exhaust-gas turbo charger system
Sealing element between depressor.Distinguishingly, the present invention relates to a kind of for coupling the flat seal of double vortex turbocharger.
Background technology
It is not simple metal but main that metal flat sealing element also is understood as those for sealing professional technician
The sealing element to be made of metal material;Such flat seal can especially include at least one sealant, this is close
Sealing is in one or both sides comprehensively or partly equipped with nonmetallic coating, such as the coating of reduction friction or abrasion.
With well known, beginning define type, be mutually directed towards positioned at the metal component for guiding hot gas
In the sealing system of flat seal between sealing surface, in sealing system, component is close by passing through metal component and plane
The installation screw of sealing or the opposite tension of other tension elements, and flat seal is squeezed using their sealing surface,
There are problems that being described below herein, this problem is exactly proved to special when sealing system is located at the exhaust gas region of internal combustion engine
Seriously:
For thermal current, these components have adjacent hot gas path, these hot gas paths lead to component sealing surface,
And sealing surface opening is formed there, these openings are interconnected via the hot gas break-through mouth of flat seal, in general,
The sealing surface on the flow direction of waste gas stream in tandem of component is open and the hot gas being located therein of flat seal is worn
Port is configured to the same in shapes and sizes, and coverage area is stacked on top of each other in the same manner.Each component is in adjacent warm
Partition wall is respectively provided between gas channel, partition wall is at least being adjacent in sectional view (along the plane for including channel longitudinal axis)
It is constructed in the form of contact pin, therefore next these partition walls should be referred to as component and connect in the member region of sealing surface opening
Piece.These component contact pin are constructed in the following manner, that is, they should be mutual using them in the case where being packed into flat seal
The end region being directed towards hermetic squeezes flat seal, that is, squeeze it is at least one be located at two component contact pin it
Between sealing plate contact pin.
When bringing into operation, internal component contact pin between adjacent hot gas path is compared to the member region on periphery
It heats quickly and more strongly, in the member region on periphery, is put down although component sealing surface equally also squeezes at runtime
Face seal, but the running temperature of the member region on periphery connects significantly lower than the internal component between adjacent hot gas path
The temperature of piece, so that the axial thermal expansion (perpendicular to the expansion of the sealing plate plane of flat seal) of component contact pin is apparent
More than the thermal expansion of the member region on periphery, only unilateral side is loaded with heat the member region on periphery by hot gas path, and
Each internal component contact pin is loaded by hot gas with heat on its both sides.Therefore, at runtime, component sealing surface with
It is occurring between flat seal, perpendicular to sealing plate plane earth orientation, accommodate in sealing plate contact pin and by sealing plate contact pin
Sealing plate area of the extruding force much than being adjacent to hot gas break-through mouth in others in the region of internal component contact pin wherein
Extruding force in domain is much greater, and at the same time, other than in the member region on periphery and sealing plate all hot gas break-through mouths
Tensioning degree significantly reduced compared to the tensioning degree before bringing into operation.
During operation in hot gas region, especially when extra high temperature occurs in exhaust gas region, the material of component exists
Plastic under high extruding force, so that the end region that is previously described, squeezing flat seal of internal component contact pin
Plastic deformation, this causes after end of run, when sealing system cools down, in sealing plate contact pin with sealing plate contact pin is accommodated
Gap is formed between internal component contact pin wherein, and even if after operation is restarted, adjacent hot gas path is just
Before the degree that detaches between each other no longer brings into operation for the first time as sealing system for gas effusion.
In traditional sealing system, aforementioned phenomenon also results in following shortcoming:Due to occurring in sealing plate contact pin region
, aforementioned high extruding force, so the flat seal in sealing plate contact pin region may also be damaged, and additionally, there may be close
The risk of the load excessive of the tension element being located at other than all hot gas paths of envelope system, they are typically to install screw, but
It for example can also be that so-called V- is combined to be.
In order to avoid leading to the component of sealing system, flat seal due to aforementioned and regional different thermal expansion
And/or tension element is damaged and is used for such sealing system, wherein, it is between component sealing surface, by flat seal
Even if the only gas to a certain extent of adjacent thermal current is eliminated in the region of the so-called seal clearance of part sealing from the beginning
The separator of close property, so that these components can freely expand in the axial direction between their hot gas path, and
Being received in sealing system seal clearance between adjacent hot gas path has internal clearance.However, because in this sealing system
In, the distance that adjacent air-flow detaches between each other is very small, so this for example in the exhaust system of internal combustion engine to exhaust gas turbine
The function of booster has detrimental effect.
